The rst paper examines how the two dimensions of heterogeneity of people in society, income disparity and ethnic diversity, affect the government formation and eventually the reallocation of income. A legislative bargaining model is constructed to investigate how political parties, whose platforms are distinguished by the ethnicity and income group they belong, form a coalition and enter a government.
The second paper analyzes the effect of criminal law reform on the behavior of agents during litigation and is coauthored with Libor Dusek. We investigate behavioral responses of judges and prosecutors to more severe punishments by analyzing the effects of Truth-in- Sentencing (TIS) laws in a large sample of individual criminal cases in the United States.
The TIS laws raised effective punishment by requiring offenders to serve at least 85% of their imposed sentence in prison. The third paper statistically documents how the relationship between economy and environmental degradation changes under the regulation and is coauthored with Milan Scasny.
We statistically decompose the change in the emission level of the various air pollutants such as SOx, CO, NOx, VOC and particulate matters (PM) in the Czech Republic.
